How to Appoint a U.S. Agent for FDA Compliance: Things You Need to Know

Foreign manufacturers entering the U.S. market must comply with strict Food and Drug Administration (FDA) regulations. One of the most critical requirements for overseas companies is the appointment of a U.S. Agent. This role is mandatory for foreign establishments involved in the manufacturing, processing, packaging, or holding of FDA-regulated products including drugs, medical devices, food, dietary supplements, cosmetics, and biologics.

Why the FDA Requires a U.S. Agent

The United States FDA enforces regulations that ensure the safety, quality, and compliance of all imported products. To maintain effective communication with foreign firms, the FDA mandates the appointment of a domestic representative. This ensures that:

• All regulatory messages reach the foreign establishment promptly
• FDA inspection notices are formally acknowledged
• Emergency notifications are handled without delay
• Submission queries and compliance discussions have a U.S.-based point of contact

Failure to designate a compliant U.S. Agent may result in delayed approvals, import refusals, enforcement actions, or removal of the company from FDA’s establishment registration database.

Responsibilities of a U.S. Agent

The U.S. Agent plays a vital regulatory and communication role. Their core responsibilities include:

1. Coordination of FDA Communications

The primary function is to receive, interpret, and respond to FDA communications. This includes notices related to establishment registration, product listing, inspection scheduling, and regulatory inquiries.

1. Support During FDA Inspections

Foreign facilities may be selected for routine or targeted inspections. The U.S. Agent assists by helping coordinate the inspection logistics, acting as a liaison, and ensuring timely responses to FDA requests.

1. Regulatory Query Management

When the FDA requires clarifications about documentation, processes, safety data, or compliance issues, the U.S. Agent helps relay information between the FDA and the foreign establishment.

1. Emergency Contact for the FDA

In urgent situations, such as product contamination, adverse events, safety triggers, or recalls, the FDA must be able to reach a domestic representative immediately.

1. Assistance With Submissions and Updates

U.S. Agents often assist with:

• Annual establishment registration updates
• Drug listing or device listing submissions
• Importer compliance documentation
• Maintaining accurate regulatory records

While the U.S. Agent does not legally assume responsibility for product compliance, they play a central role in ensuring the FDA receives necessary information on time.

Which Companies Must Appoint a U.S. Agent?

FDA rules require a U.S. Agent for:

• Drug manufacturers, repackers, or relabelers (per FD&C Act Section 510)
• Medical device manufacturers registering under 21 CFR Part 807
• Food facilities under the Food Safety Modernization Act (FSMA)
• Cosmetic manufacturers entering the U.S. market
• Dietary supplement and nutraceutical firms
• Biologic and vaccine facilities
• API manufacturers and contract development companies

If a company operates multiple foreign facilities, each establishment must appoint a U.S. Agent individually.

Criteria to Consider When Choosing a U.S. Agent

Appointing a U.S. Agent is not a formality—it is a long-term compliance partnership. When selecting a U.S. Agent, companies should evaluate the following:

1. Regulatory Knowledge

The agent must understand FDA frameworks such as:

• Drug and device registration rules
• eCTD submissions
• Import compliance requirements
• Safety reporting obligations
• FSMA rules for food facilities

1. Responsiveness

The FDA may require rapid replies. A compliant U.S. Agent must be available to respond promptly, especially during emergencies.

1. Experience in Handling Inspections

Agents with experience in FDA inspections, Form 483 responses, and regulatory communication help minimize compliance risks.

1. Confidentiality and Data Security

Handling regulatory filings requires secure data practices and confidentiality agreements to protect sensitive information.

1. Ability to Support Global Regulatory Strategy

Many professional agents offer additional services:

• DUNS number support
• Labeling compliance
• Importer of Record guidance
• Submission publishing
• Regulatory consulting

Such capabilities add value during the entire lifecycle of U.S. market entry.

Steps to Appoint a U.S. Agent

Step 1: Select an Authorized U.S.-Based Individual or Firm

The foreign company must first identify a suitable representative within the United States.

Step 2: Provide Establishment Information

Details such as establishment name, address, DUNS number, product categories, and regulatory activities must be shared.

Step 3: Add the U.S. Agent During FDA Registration

During FDA Facility Registration (for drugs, devices, food, or cosmetics), the foreign establishment lists the appointed U.S. Agent.

Step 4: Agent Confirms Appointment

The U.S. Agent must confirm acceptance through FDA systems such as:

• FDA Unified Registration and Listing System (FURLS)
• Device Registration and Listing Module
• Food Facility Registration Portal

Step 5: Maintain Communication and Annual Updates

FDA registrations must be renewed annually. The U.S. Agent must continue to represent the company and respond to any FDA notices throughout the year.

Consequences of Not Appointing a U.S. Agent

Non-compliance with the U.S. Agent requirement can result in:

• Foreign establishment registration rejection
• Import refusal of shipments
• Delay in marketing authorization
• Removal from FDA active registration database
• FDA inability to communicate, triggering administrative holds

Maintaining a reliable U.S. Agent is therefore essential for uninterrupted business operations.

• Avoid registration errors
• Navigate FDA correspondence professionally
• Reduce inspection risks
• Maintain continuous compliance
